    Important Safety Instructions 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instruc- tions.
  • Page 3 Please read this entire user’s manual so that you can understand all the features and get the most from the PL-1. The Warranty is on a separate card. Read it and send it in to get full war- ranty coverage.

    40 seconds, will glow green. About 4 second after that a faint click will be heard, indi- cating the muting relay turning off. The PL-1 is now ready for use. If the power is removed, even briefly, then restored, the warm-up time delay process will start over again.
  • Page 5 (100 × required value) All moving-coil cartridges require a load resistance, and sometimes a load capacitance. The PL-1 allows the opti- mum load to be selected by inserting the load resistors or capacitors into the ZIF Socket. The 3M TexTool® ZIF (Zero Insertion Force) Socket, originally designed for the semiconductor industry, provides a convenient way to attach additional shunt resistors or capacitors.
